Costco Hours

Like many of you out there we can never remember what the Costco opening hours are, so we put up this post for everyone else who needs this info! Most of the Costcos standard operating hours are identical, so we will list the main operational hours below. Something else to think about is that Costco hours for some of their specialty in store departments such as Costco optical or Costco bakeries often differ from their standard operation times. So if you intend to visit one of their specialty departments, then it is probably best if you ring up their customer service line on 1-800-774-2678 to find out their opening hours.

Standard Operating Hours

MON – FRI
10am – 8:30pm

SATURDAY
9:30am – 6pm

SUNDAY

Special Operating Hours

Costco has different operating hours for certain holidays and occasions. Below you can find where these times differ.

New Years Eve: 9:00am – 6pm

New Years Day: Not open

Please keep in mind these the above listed times are standard hours for most branches. Some of the smaller branches out there do have slightly shorter opening hours, so please remember this. If you are unsure if your local branch is one of these then you can ring the customer service line on 1-800-774-2678 to double check.
